The phrase "machinability" is used to describe or suggest how well a material, such as stainless steel, can be worked by a cutting tool. Different machining processes are needed when working with different grades of stainless steel since they differ from other steel grades like carbon steels in terms of their physical and mechanical characteristics.
In comparison to carbon steels, whose relative machinability is 100, austenitic grades of ss machined washer have a relative machinability of around 50 in an annealed condition. Due to stainless steels' tendency to be tough rather than hard, this difference can be seen. The tendency of stainless steel to seize and gall is due to this.
The three grades of stainless steel that are machined the most frequently are 202, 304, and 316. The three grades of stainless steel—202, 316, and 304—are all austenitic grades. These stainless steel grades differ from one another due to compositional changes. For instance, the 202 grade stainless steel machine washers are largely alloyed with chromium, nickel, and manganese. While the alloys of both grades 304 and 316 tend to be predominately composed of both chromium and nickel.
Long, gooey chunks are created when grade 202 stainless steel is machined. The annealed condition of stainless steel grade 202 is also suitable for machining. The material is heated by soaking it at 1038°C for 30 min, then cooling it to below 16°C to complete the martensite transition. Although the material can be welded using conventional fusion and resistance techniques, the oxyacetylene welding technique should not be used to join this grade of steel. AWS E/ER630 is the suggested filler metal for this alloy. Pre-soaking the alloy for an hour at 1177 °C can be used to forge the ss 202 machined washer. It is not recommended to forge the alloy below a temperature of 1010°C.
During deformation, alloys 304, 304H, or 304L are susceptible to work hardening. During machining, chip breaking is applied to this washer made of stainless steel 304. The best machining outcomes are seen when this grade is machined using a combination of slower speeds, proper lubrication, heavier feeds, sharp tools, and strong rigid equipment. In addition to being a highly well-liked alloy, 316 has a 5.6 machining cost factor in comparison to carbon steel grade 12L14. Since grade 316 may be easily cold worked, stainless steel 316 machined washer is advised for welding.
